摘　　要：皖南障公山地区位于江南古隆起带北东部,属于障公山锡金—铜金成矿带西部,金属矿化活动强烈,有多处金属矿床,隐伏构造岩浆岩带的地球物理异常明显,成矿元素具有相对富集的特征。文章通过系统总结该区地质背景及地球物理、地球化学特征,认为区内金锑铅锌多金属矿与断裂构造关系密切,成矿元素具有相对富集的特征,在深部热液作用下出现活化转移,进而可在有利部位富集成矿,但多数锑矿中不含金,以单独矿化形式出现。为该地区及邻区今后找矿提供理论支撑。The zhanggongshan area in southern Anhui is located in the northeast of Gangnam ancient uplift belt and belongs to the west of zhanggongshan tin copper gold metallogenic belt.There are many metal deposits with strong metal mineralization activity.The geophysical anomaly of concealed tectonic magmatic rock belt is obvious,and the metallogenic elements are relatively enriched.By systematically summarizing the geological background,geophysical and geochemical characteristics of this area,it is considered that the Au Sb Pb Zn polymetallic deposits in this area are closely related to fault structures,and the ore⁃forming elements are relatively enriched.They are activated and transferred under the action of deep hydrothermal solution,which can enrich integrated deposits in favorable parts,but most antimony deposits do not contain gold and appear in the form of separate mineralization.It provides theoretical support for future prospecting in this area and its adjacent areas.
